Final answer:
The division of the nucleus during the eukaryotic cell cycle is referred to as mitosis, which involves several phases including prophase, metaphase, anaphase, and telophase, culminating in two genetically identical daughter cells.
Step-by-step explanation:
The Division of the Nucleus During the Eukaryotic Cell Cycle
The division of the nucleus during the eukaryotic cell cycle is a complex process called mitosis. Mitosis is a multi-phase process that results in the division of one nucleus into two genetically identical nuclei. The eukaryotic cell cycle consists of interphase and the mitotic phase. Interphase itself is divided into three phases: G1, S, and G2. During these stages, the cell grows, duplicates its DNA, and prepares for cell division.
The mitotic phase includes both mitosis and cytokinesis. Under mitosis, there are four phases known as prophase, metaphase, anaphase, and telophase. This is when the actual division of the nucleus occurs. The chromatids separate and are evenly divided between the two new daughter cells. Following mitosis, cytokinesis completes the cell division process by dividing the cytoplasm, resulting in two separate cells.
